The song originally featured on Fender’s third and latest studio album ‘People Watching’, but later took on new life during his huge London Stadium gig last year, when he brought Dean out in front of the 80,000-strong crowd and performed a collaborative rendition.

The two of them would then join forces twice more at shows to share the duet – both held at Fender’s huge homecoming shows at Newcastle’s St. James’ Park, and last June, they officially released the track.

Since then, it’s become a fan-favourite, winning the BRIT Award for Song Of The Year, and scoring Fender his first ever Number One single. The track broke the record for the most consecutive weeks spent in the Top 40 before reaching the top, and has now spent nine non-consecutive weeks at number one on the UK Singles Chart.

To celebrate, Fender and his saxophonist, Johnny “Blue Hat” Davis, surprised fans at Dean’s headline show at The O2 on Friday (May 1) to perform together for the first time this year.
